A) Avoiding foods rich in vitamin K.
B) Increasing the intake of leafy green vegetables.
C) Reducing the consumption of foods high in iron.
D) Limiting the intake of vitamin C-rich foods.

Answer 1

When providing dietary teaching for a patient receiving warfarin (Coumadin) therapy, it is important to avoid foods rich in vitamin K. Additionally, the patient should be informed about potential interactions with other medications and supplements.

Step-by-step explanation:

When providing dietary teaching for a patient receiving warfarin (Coumadin) therapy, it is important to avoid foods rich in vitamin K. Vitamin K can interfere with the effectiveness of warfarin as it counteracts its anticoagulant effect. Foods such as green leafy vegetables (cabbage, spinach), cauliflower, soybean, and wheat germ are all high in vitamin K and should be limited in the patient's diet. Additionally, it is crucial to inform the patient about the potential interactions between warfarin and other medications or supplements. For example, vitamin C-rich foods should be limited as they can increase the patient's risk of bleeding. Iron-rich foods should also be consumed in moderation as they can interfere with the absorption of warfarin.
